I love that it goes back to MOS 6502, Zilog Z80 etc. It also includes the WDC 65C02 which is still in production.

The actual link to get the .tar.gz archive is http://cpudb.stanford.edu/cpudb.1416196069.tar.gz http://cpudb.stanford.edu/cpudb.1416196069.tar.gz (on the download page, both links points to the .zip file). They are basically the same size anyway (~728kiB). A few interesting charts showing the evolution of CPUs: * Transistor size (http://cpudb.stanford.edu/visualize/technology_scaling http://cpudb.stanford.edu/visualize/technology_scaling): the process is still regularly scaling down * Clock frequency (http://cpudb.stanford.edu/visualize/clock_frequency http://cpudb.stanford.edu/visualize/clock_frequency): processors do not tick significantly faster than 4GHz, a speed they reached in 2004/2005 * Performance (http://cpudb.stanford.edu/visualize/performance_by_freq_and_cache http://cpudb.stanford.edu/visualize/performance_by_freq_and_...): I am still unable to display this graph The clock frequency graph shows a processor at 21.3GHz. It's the Z3480, whose clock actually ticks at 2.13GHz (http://ark.intel.com/products/70102/Intel-Atom-Processor-Z3480-1M-Cache-up-to-2_13-GHz http://ark.intel.com/products/70102/Intel-Atom-Processor-Z34...).

Is it down? Any mirrors?

  It seems so. Here is the mirror on archive.org https://web.archive.org/web/20141013114803/http://cpudb.stanford.edu/ https://web.archive.org/web/20141013114803/http://cpudb.stan... I've seen this happening several times after submission to HN.

    It would be slashdot effect if slashdot was still relevant.

      On Spain is called "Meneame" effect

Interesting. Pity it does not feature anything DEC beyond Alpha.

A link to the ISSCC keynote by Mark Horowitz, curator of cpudb. IMO worth a listening to for most anyone interested in CPU performance related issues. http://isscc.org/media/2014/plenary/Mark_Horowitz/NewStandardPlayer.html?plugin=HTML5&mimetype=video%2Fmp4 http://isscc.org/media/2014/plenary/Mark_Horowitz/NewStandar... The plots shown in his presentation basically show off the underlying data in cpudb.

  Interesting talk. ISSCC also offers an edx crash course ISSCCx ISSCC Previews - Circuit and System Insights (https://courses.edx.org/courses/IEEEx/ISSCCx/3T2014/info https://courses.edx.org/courses/IEEEx/ISSCCx/3T2014/info)
